Glaucoma secondary to aphakia and intraocular lens

The incidence of secondary glaucoma after cataract surgery varies greatly with the changes in the age of the literature, and is related to the improvement of eye microsurgery techniques. Generally speaking, the intraocular pressure increase and glaucoma after cataract surgery are less in phacoemulsification than in extracapsular surgery. Extracapsular surgery is less than intracapsular surgery. Intraocular lens implantation is better than intracapsular surgery. Ciliary sulcus implantation is less, posterior chamber type of intraocular lens is less than anterior chamber type and iris type intraocular lens. In recent years, cataract extraction and intraocular lens implantation have made rapid progress, especially the improvement of surgical methods of seamless wire incisions, intraocular lens implantation, development and application of various viscoelastic agents, improved design of new intraocular lenses and ultrasound The promotion of emulsification surgery, the increased intraocular pressure and the incidence of glaucoma have gradually decreased after non-phakic and intraocular lens surgery, but at the same time, due to the surgery of complex cases, some new problems such as intraocular lens suspension surgery, with iris septum Implantation of intraocular lens and intraocular contact lens implantation of the eye with lens. If a sustained increase in intraocular pressure occurs, it will cause irreversible damage to its visual function. As a popular cataract rehabilitation surgery, it is important to understand and recognize the increased intraocular pressure and the occurrence of glaucoma after surgery.
